Effect of Laser Process on the Seedling and Root System Growth of the Chinese Pine

研究了用激光处理油松种子对其幼苗地上部分和地下部分的影响。结果表明,处理组比对照组的苗高增加59%,地径增长37%,地上部分干质量增长52%,主根长增加36%,侧根数增加43%,根系干质量增长108%。表明激光处理油松种子对其幼苗和根系生长有积极增强效应。

Effect of laser process Chinese pine on the seedling growth of both aerial and underground part is studied. The experiment showed that compared with the reference sample, the height of seedling increased 59% the diameter increased 37%, the dry mass of aerial part increased 52%, the length of taproot increased 36 %, the number of lateral roots increased 43%, the dry mass of root system increased 108 %. The results showed that the laser process on Chinese pine has a positive effect on the Growth of the both seedling and root system.
